Abstract: Disclosed are a near-eye display apparatus. The near-eye display apparatus comprises: a display screen; a polarization converter; an imaging lens group; a semi-transparent and semi-reflective layer arranged between the polarization converter and the first lens; a reflective polarized layer arranged on the side, facing away from the polarization converter, of the semi-transparent and semi-reflective layer, the polarization direction of the first linearly polarized light is vertical to the polarization direction of the second linearly polarized light; and a liquid crystal lens arranged between the semi-transparent and semi-reflective layer and the reflective polarized layer. When the liquid crystal lens is switched between the first phase retardation amount and the second phase retardation amount, the light path of light in the near-eye display apparatus changes, so that the near-eye display apparatus can image at two focal lengths.

Abstract: An optical system includes at least one first display module, at least one second display module, and a first optical element. The first optical element includes a first light incident surface, a second light incident surface, and a viewing surface. The first light incident surface is configured to transmit imaging light emitted from the at least one first display module into the first optical element and refract it onto the second light incident surface. The second light incident surface is configured to transmit imaging light emitted from the at least one second display module into the first optical element and refract it onto the viewing surface, and reflect the imaging light transmitted into the first optical element through the first light incident surface onto the viewing surface. The viewing surface is configured to transmit the imaging light emitted from all display modules to a human eye.

Abstract: A display panel, a display device and a display method. The display panel includes a first microlens array, a pixel island array and a second lens. The pixel island array is configured to display a plurality of sub-original images. The first microlens array is configured to converge light emitted from the plurality of sub-original images so as to obtain imaging light, and the imaging light is capable of forming a first virtual image. The second lens is on a user viewing side of the display panel relative to the first microlens array, and the second lens is configured to converge the imaging light so as to obtain a second virtual image. The first virtual image is a virtual image in which the plurality of sub-original images are stitched and enlarged, and the second virtual image is an enlarged virtual image of the first virtual image.
